1978 Jaguar XJ — Problems, Recalls & Complaints

EXCESSIVE FUEL VAPOR PRESSURE CAN OCCUR THAT, AFTER PROLONGED CYCLING, COULD WEAKEN THE FUEL TANK STRUCTURE.

Remedy: INSTALL A REVISED FUEL PURGE SYSTEM WHICH ELIMINATES EXCESSIVE VAPOR PRESSURE BUILD-UP.

THE AIR PIPE AND FUEL LINE PIPE MAY CONTACT EACH OTHER AND RESULT IN CHAFING OF THE FUEL RAIL.

Remedy: THE DEALER WILL REROUTE AIR OR FUEL LINE TO PRECLUDE CONTACT, WITHOUT CHARGE TO OWNER.

THE EXHAUST DOWNPIPES INSTALLED ON THE INVOLVED VEHICLES MAY NOT PERMIT PROPER CLEARANCE BETWEEN THE DOWNPIPES AND THE STEERING COLUMN LOWER JOINTS. UPON MAKING A HARD FULL RIGHT TURN, THE EXHAUST DOWNPIPE AND STEERING COLUMN COULD COME INTO CONTACT WITH EACH OTHER. THIS COULD RESULT IN A LOSS OF STEERING CONTROL.

Remedy: DEALER WILL INSPECT AND, IF NECESSARY, REPLACE THE EXHAUST DOWNPIPE WITH ONE OF MODIFIED SHAPE, WITHOUT CHARGE TO OWNER.

THE SELECTOR QUADRANT SPIRAL RETAINING PIN MAY WORK ITS WAY OUT OF POSITION SO THAT THE VEHICLE COULD REMAIN IN GEAR WHEN SELECTOR LEVER IS MOVED INTO THE "PARK" POSITION.

Remedy: DEALER WILL SECURE SPIRAL PIN USING A RETAINING PIN TO PERMANENTLY LOCK IT IN POSITION.

UNDER A COMBINATION OF CIRCUMSTANCES IN COLD WEATHER, ICING MAY PREVENT RETURN OF THE THROTTLE BUTTERFLY TO THE IDLE POSITION.

Remedy: THE DEALER WILL FIT COOLANT HEATED THROTTLE BODIES ON ALL VEHICLES AT NO COST TO OWNERS.
